I was into IPSC at the time. One of my fellow IPSC buddies was starting a CAS club at the same range. I went out to watch a match and slowly got hooked. The thing I like the best is getting to shoot more than just one or one type of gun. I want to be a well rounded good shot, and this is one way to do that.
Also as mentioned, not too many gamers, and a whole bunch of really nice folks.
